Specification of Letters Patent.

Paeentearan. 8,1907.

Application led October` 8, 1906. Serial No. 338,048.

To all whom it may concern:

, Be it known that we, MATHEW E. ROTI- BERG and ALFRED ERNs'r, citizens of.the United States, residents of Pittsburg, in the county of Allegheny and State of Pennsyl- Vania, have made a certain new vand useful.E

Invention in Coke-Ovens and we declare the following to be a full, clear, and exact description of the same, such as will enable others skilled in the art to which it appertains to make and use the invention, reference being had to the accompanying drawings, and to letters of reference marked thereon, which form a part of this specification.

Figure 1 represents vertical half-sections taken through the heating-flues in the side walls and through theoven-chamber on the lines 1 1 and 1a la. Fig. 2 is a horizontal section on the line 2 2,r Fig. 3'. Fig. 3 is a vertical section on the line 3 8, Fig. 2. Fig. 4 is a section on the line 4 4, Fig. 5, the upper part of the ovens being shown in side elevation. Fig. 5 is a section on the line 5 5,' Fig. 4.

The invention relates to coke-ovens, having for its Vobject the provision of means for obtaining a uniform distribution of heated air to the combustion-chambers of lovens having heating-fines in the side Walls thereof between adjacent coking-chambers.

The'invention is shown as applied to the oven disclosed in 'our pending application, Serial No. 305,351, allowed August 17, 1906.

The invention consists in the novel construction and combinations of parts, as hereinafter sct forth.

In the accompanying drawings, illustrating the invention, the letters A A designate the coking-chambers, and B B revertmg hcating-ilucs in the side walls of such chambers, laterally opposite series of such flues boing shown as providcd in each dividingwall B between adjacent coking-chambers at each side of the transverse center partition A in the hollow wall. The series of ilues, of which there are shown four in eachside wall,

-are thus also shown as arranged endwise operal extensions C, with flue D, located und er the oven-chamber, a downward-directed passage E connecting-each ilue D with a central waste-gas main F in the foundation running longitudinally of the oven-battery. The waste-gas main F extends beyond the battery of ovens at one end thereof, where it is provided with a butterfly-valve G, controlling the communication of the main` F with flanking regenerator-chambers H H at each side. These regenerator-chambers extend beyond the ovens at each end and beyond the main F at one end into communication with the stack l, the opening to which is controlled by a butterfly-valve J, which cuts off one chamber from communication with the stack, while it throws the other chamber into communication therewith in an alternate manner.

K is a fan located outside of the oven-battery between the stack I and the termination of the main'F at one end of the ovens and which, through passage K', communicating with fines L in the floor of the ovens, establishes a circulation of air, blowing the same,

through the medium of the butterfly-valve M, into one end of the regenerator-chambers H H alternately and through the medium of a similar valve N controlling the communication of the other ends of said chambers with hot-air mains O O alternately from said chambers into the hot air mains, These hot-air mains O O run lon itudinally in the oven foundation laterally of the regeneratorchambers and have connection with the combustion-ch ambers in the side walls of the ovens in the following manner.

At regular intervals hot-air flues P P extend upward from the hot-air mains O O to the same height as the horizontal flues-B B, said hot-air flues being located at the sides of the oven-battery in the walls B between adjacent coking chambers. Each couple of vertical .branch flues P P at opposite sides of the kbattery are connected at the upper portion of the wall B by horizontal transverse passages R R,'located between the laterally-opposite series of heating-dues B B in such side wall. These passages -R R, two of which are shown in each wall B for each couple of laterally-opposite series of heating-dues, have short lateral extensions r rr at short and regular intervals throughout' their length, connecting the passages with the uppermost flue B and with the third flue B from the top of each series.

As shown, they passages R R, connecting` IOO' double character, having a long branch b at each side of the wall B near the lues B, the walls B being pierced at each side between such long branches b and the heatingO-ues to form the lateral extensions 1 r, each having thus separate communication with a series of flues B. The long branches b are connected at the ends by short branches b', communicating at the center with the lues P at p. In this manner the heated air. 'which is supplied from the hot-air mains in the roundation,l has regular distribution directl5T throughout the length of the upper heatingflues B, and the direction of the draft being downward through all of the iues B to the waste-gas main the combustion reaches a maximum of perfection.

The gases liberated from the charge of coal in the ovens pass through flues U to the gasmain V, by which they are conducted in the usual manner to a condensing-house (not shown) for the removal of the tar and ammonia. The gases are then returned to the ovens by piping, which is in connectionwith the feed-pipes W W, having burner connections X X, located in the heating-fines.

` The supply of air to the heating-iues in the 3o the ovens, airl being drawn in t side walls is continuous and moves in .the same direction throughout the o eration of rough the ilues L in the licor of the ovens by the fan K and blown through the regenerator-chambers H H and the hot-air mains 0,() alternately. From each hot-air main O the air is continuously supplied to the heating-fines in the side walls. The air-supply is at the same time continuously heated by the waste gases of combustion, which are drawn in a continuous manner from the heating-fines into the central waste-gas main F, from which they'are drawnv through the regenerator-chambers H Halternately. From these chambers the wastegases pass continuously and in the same direction to the stack.
